XSL-FO背景圖像損壞生成pdf

[英]XSL-FO background image corrupting generated pdf

問題描述

我正在從下面的xsl文檔生成PDF。 我正在嘗試添加背景圖像以覆蓋整個生成的pdf，但是當我在第12行中<fo: block-container>時，它會不斷破壞pdf生成？我還有另一種方式可以生成背景圖像嗎？我在這里做錯了什么？

我還嘗試使用<fo:external-graphic>包括背景圖像，該圖像的確顯示了圖像，但在頂部留了一個邊框（我認為是之前的區域）。 但這僅適用於托管圖像網址，不適用於本地存儲的圖像，這不是問題，但我發現有些奇怪。

<fo:block text-align="center" display-align="before"> <fo:external-graphic top="-20mm" bottom="-20mm" content-width="210mm" height="150mm" src="url()"> </fo:external-graphic> </fo:block>
